Surround ONLY works with 3 monitors =(, they're are programs and hacks around this, I do not remember them sadly, nor did they work great..... The best I found was some program that made all windowed screens stretchable, and I would stretch the games horizontal across the screens and it would work to an extent... I do not remember it though. Troll around Google for a bit theirs bound to be something.
Other than that, it isn't worth your time, nothing on 2 screens is any good at all with the bezel being in your center point of view.
